The Postal Accountability and Enhancement Act of 2006 (PAEA) fundamentally altered the U.S. Postal Service by introducing enhanced pricing flexibility, profit incentives, and potential antitrust liability. PAEA also mandated a change from breakeven, cost-of-service regulation where revenues must equal costs over time to price cap regulation. The Postal Service can now introduce new or modify ex...

The attraction between electrons and holes in semiconductors forms excitons, which largely determine the optical properties of the hosting material, and hence the device performance, especially for low-dimensional systems. Mono- and few-layer black phosphorus (BP) are emerging two-dimensional (2D) semiconductors. Despite its fundamental importance and technological interest, experimental invest...
